The SETI Institute, established in 1984, is a not-for-profit research organization whose mission is to explore, understand, and explain the origin and nature of life in the universe. The acronym SETI stands for the “search for extraterrestrial intelligence”. The institute is headquartered in Mountain View, California, and consists of three primary centers.
The Carl Sagan Center, named in honor of the famous astronomer and science communicator, is home to over 80 scientists and researchers. They focus on six research areas: astronomy and astrophysics, exoplanets, planetary exploration, climate and geoscience, astrobiology, and SETI. The researchers aim to understand the nature and proliferation of life in the universe.
The Center for Education promotes STEM education through various programs aimed at teaching and inspiring children, young adults, and educators in physical sciences with an emphasis on astronomy and astrobiology.
The Center for Public Outreach brings the work of the SETI Institute to the general public through its weekly radio broadcast and podcast – “Big Picture Science” and the weekly lecture series “SETI Talks.”
The SETI Institute employs over 100 researchers that study all aspects of the search for life, its origins, the environment in which life develops, and its ultimate fate. Despite the high-profile nature of its work and its popular appeal, the SETI Institute has faced ongoing challenges in securing funding and achieving mainstream scientific acceptance.
History
The SETI Institute, incorporated as a 501(c)3 California Non-Profit Corporation on November 20, 1984, was established to explore the possibilities of life in the universe. The inaugural officers of the Institute were CEO Thomas Pierson and SETI scientist Jill Tarter, and the Institute began operations on February 1, 1985.
Before the SETI Institute’s inception, NASA was funding a small project in the search for extraterrestrial intelligence. Discussions about maximizing the effectiveness of the funds led to the concept of a dedicated non-profit research organization focused on research and education around the factors of the Drake Equation, which estimates the number of civilizations in our galaxy with which we might communicate.
The first Trustees of the newly-formed SETI Institute were Frank Drake, Andrew Fraknoi, Roger Heyns, and William Welch. Over the years, well-known figures such as Carl Sagan, Lew Platt, and Nobel Prize winners Baruch Blumberg and Charles Townes have served on the Board of Trustees.
The first grant-funded proposal at the Institute was for SETI research, led by Jill Tarter. The first astrobiology grant was received shortly thereafter, with Harold Klein as the Principal Investigator. Hundreds of research and education grants have been successfully managed at the SETI Institute since those first few awards.
The SETI Institute has been led by several CEOs, with current President and CEO Bill Diamond taking charge in June 2015. The Institute has undergone restructuring, folding the SETI research program into the larger science umbrella of the Carl Sagan Center. Education and Public Outreach has always been an integral part of the Institute, including space science and astrobiology curricula for formal and informal education, the popular radio show/podcast Big Picture Science, the SETI Talks lecture series, public lectures by scientists, and popular science writing.
Structure and Organization
The SETI Institute, incorporated in 1984, is a not-for-profit research organization with a mission to explore, understand, and explain the origin and nature of life in the universe. The institute consists of three primary centers:
- The Carl Sagan Center: Named in honor of Carl Sagan, this center is home to over 80 scientists and researchers. They focus on six research areas: astronomy and astrophysics, exoplanets, planetary exploration, climate and geoscience, astrobiology, and SETI. The researchers aim to understand the nature and proliferation of life in the universe.
- The Center for Education: This center promotes STEM education through various programs aimed at teaching and inspiring children, young adults, and educators in physical sciences with an emphasis on astronomy and astrobiology.
- The Center for Public Outreach: This center brings the work of the SETI Institute to the general public through its weekly radio broadcast and podcast – “Big Picture Science” and the weekly lecture series “SETI Talks.”
The SETI Institute employs over 100 researchers that study all aspects of the search for life, its origins, the environment in which life develops, and its ultimate fate. Most of the research undertaken within the Carl Sagan Center is funded by grants from NASA, while SETI endeavors are funded exclusively by private philanthropy. The institute’s SETI researchers use both radio and optical telescope systems to search for deliberate signals from technologically advanced extraterrestrial civilizations.
Functions and Operations
The SETI Institute (Search for Extraterrestrial Intelligence) is a non-profit research organization whose mission is to explore, understand, and explain the origin and nature of life in the universe, and to apply the knowledge gained to inspire and guide present and future generations. It has a passion for discovery and for sharing knowledge as scientific ambassadors to the public, the press, and the government.
The SETI Institute has three primary areas of activity:
- Research: The Institute conducts research in a wide range of fields including astronomy and planetary sciences, chemical evolution, the origin of life, biological evolution, and cultural evolution. The research is carried out by scientists who are leading experts in their respective fields.
- Education: The Institute is deeply committed to education and public outreach. Its programs are designed to reach diverse audiences, from school children to adults. The Institute’s scientists often participate in public lectures, radio and television broadcasts, and other public events.
- Public Outreach and Dissemination of Information: The Institute communicates the results of its research and the scientific knowledge existing in the fields of its interest to the public. It does this through a variety of means, including its website, public lectures, and media appearances.
The SETI Institute is perhaps best known for its efforts to detect extraterrestrial intelligence. Scientists at the Institute use both radio and optical telescopes to search for deliberate signals from technologically advanced civilizations. However, this is just one aspect of the Institute’s work. The Institute’s scientists also study the formation and nature of stars, planets, galaxies, and life itself, seeking to understand the many pathways that might lead to a living or technological civilization.
Controversy
The SETI Institute has been the subject of controversy, particularly around the topic of Messaging to Extraterrestrial Intelligence (METI). The debate centers on whether we should actively send messages into space, potentially alerting extraterrestrial civilizations to our existence, or simply listen for signals.
This controversy was ignited in 1999 when a team of radio astronomers at the Evpatoria Radar Telescope in Crimea, led by Alexander Zaitsev, sent an interstellar message called ‘Cosmic Call’ to four nearby sun-like stars without consulting with other members of the SETI community. This project was funded by an American company called Team Encounter, which allowed the public to submit text and images for the message in exchange for a fee.
The decision to send these messages sparked a divisive debate among scientists and scholars. Critics argue that such actions could pose a risk to humanity by revealing our presence to potentially hostile alien civilizations. They call for a broad international and public discussion on the matter and a temporary moratorium on such transmissions.
On the other hand, some scientists, like SETI Institute radio astronomer Seth Shostak, argue that such deliberations are pointless. They contend that signals already leak into space from radio and television broadcasting, and from civilian and military radar. Shostak maintains that extraterrestrial civilizations with technology even a few centuries in advance of ours could detect this radio leakage.
Work in Ufology
The SETI Institute’s work in Ufology primarily revolves around the scientific investigation of Unidentified Flying Objects (UFOs) and the hypothesis of extraterrestrial life. The idea that extraterrestrial beings might inhabit the cosmos is not new, and modern surveys suggest that approximately 80% of the American populace think it’s likely that aliens exist on other worlds.
The SETI Institute focuses on the UFO hypothesis, which suggests that there are extraterrestrials visiting Earth now or in the historical past. Modern UFO sightings began just after the Second World War, and the Institute has been involved in the scientific investigation of these phenomena.
However, the SETI Institute maintains a skeptical stance towards most UFO sightings. Despite the large number of UFO sightings reported annually in the U.S., the Institute points out that interstellar travel is exceedingly difficult and would require extraordinary amounts of energy. They also argue that any aliens would need a good motivation to undertake such a journey, and becoming involved in human affairs seems highly improbable.
The SETI Institute has also commented on the Navy videos from 2017, which showed strange shapes that seemed to twist in the sky or quickly pass beneath the aircraft. While these videos are intriguing, the Institute suggests that there are several possible explanations for what’s seen in these videos that don’t involve alien spaceships.
In conclusion, while the SETI Institute acknowledges the possibility of extraterrestrial life and investigates UFO sightings, it maintains a scientific and skeptical approach to these phenomena.
